What is another name for hepatitis B?

The term HBV refers to the virus that can infect liver cells. Infection may be short-lived or may continue for a long time. Some people have no noticeable symptoms, while others develop tiredness, nausea, discomfort under the ribs, dark urine, or yellowing of the skin and eyes. A symptom such as dark urine can have many causes and does not by itself identify hepatitis B.

A clinician may use blood tests to check for the virus and to understand whether the liver is inflamed. A liver function test can be part of that assessment, alongside other hepatitis B tests.

If a result, letter, or conversation mentions HBV, ask which test was positive and whether it indicates a current infection, a past infection, or immunity. Avoid sharing toothbrushes, razors, or items that may carry blood, and cover open cuts. Do not stop prescribed medicines without advice. Household or sexual contacts may need tailored testing or vaccination advice.

Arrange a GP consultation to review the result and decide whether repeat testing, liver assessment, or specialist care is appropriate. Hepatitis B vaccination helps prevent infection for people who are not already protected.

Seek prompt medical advice for new yellowing of the eyes or skin, very dark urine with marked tiredness, persistent vomiting, increasing abdominal swelling, confusion, or unusual bleeding. These symptoms need assessment because they can signal significant liver or general illness, whether or not hepatitis B is the cause.

Ask: What does my HBV result show? Do I need liver function tests or repeat blood tests? Should people close to me be tested or vaccinated? Are there medicines, supplements, alcohol, or activities I should avoid while this is being assessed?
